ABSTRACT:
An oil pump unit for an internal combustion engine can reduce the number of component parts to configure a simplified pump case, reducing the size and weight thereof. In an oil pump unit has a case cover put on the outside of a crankcase via a spacer and an oil tank chamber formed by the inside surface of the case cover and the spacer. The spacer is formed inside an outer circumferential wall thereof with a division wall which partitions the oil tank chamber from a crank chamber and with one pump case half-body portion forming a half-body of a pump case of an oil pump. Another pump case half-body is joined to the pump case half-body portion to form the pump case. The pump case half-body portion is formed in a lower portion thereof with an oil suction port communicating with a bottom portion of the oil tank chamber.
